Somebody suggested that I should make a new thread so it can be made into a sticky.

I have had a few people confirm that this worked for them also, but I would like to hear from all you Roadster owners.

It is rather simple to eliminate the channel switching lag in the Roadster. All you have to do is leave the reverb button on the footswitch engaged at all times, regardless of if you have reverb on in the channel strip or not. There will still be the lag on the different levels of reverb mixing in, but the amp is actually designed to do that and with good reason. Nonetheless, there will be absolutely no dead spot in sound.

Couple this with cycling through the channels whilst in standby to eliminate the "pop" and you are ready to rule the road!

I can say that I've never had my reverb off... LOL.. that might explain why I don't notice the lag. I tend not to change channels much while playing songs... sometimes when I am practicing I do to see what it would sound like with differing amounts of gain.
